Fluid end valve and seats refers to the kit consisting of Fluid body, Fluid seat, and Fluid rubber. The valve assembly is an important part of the hydraulic end of the drilling mud pump, which plays a role in allowing the mud to pass through in one direction.
Fluid end valve and seats are a one-way valve. At present, the common ones are No. 6 and No. 7, as well as API No. 6 and API No. 7. The fracturing truck is equipped with a valve assembly, which is only smaller, and it is customary to call it No. 5 in the market. We use 20CrMnTi forging, carburizing and quenching to create fluid end valves and seats. There are many manufacturers producing Vall assembly, and the quality is also uneven, so I hope you can pay more attention when purchasing.
Fluid end valve and seats are generally composed of a valve shell, an internal valve ball and a valve seat. When the fluid passes through the valve, the valve ball leaves the valve seat, the flow channel is opened, and the fluid can pass through. When the fluid flows in the reverse direction, under the action of pressure (or other force), the ball sits on the seat of the ball, the flow channel is closed, and the fluid cannot pass through the ball. The principle is basically like this. Valves are often used on pumps, especially multi-piston pumps, to maintain one-way flow of fluid.
1. According to the valve structure of the pump, it can be divided into: ball valve, gate valve, disc valve, plunger valve, etc.
2. According to the purpose, it can be divided into: check valve, throttle valve, overflow valve, distribution valve, etc.
In simple terms, it is a "valve". Assembly is a commonly used term in the mechanical field. Assemblage means aggregate. A series of parts or products form a whole that realizes a specific function. The general name of this system is an assembly. For example: the headlight assembly on the car, the engine power assembly, the transmission assembly and the gear assembly and so on.
To sum up, the fluid end valves and seats are the valve assembly, which is the entire system (various parts of the valve) that constitutes the valve.
